. and State of.Missouri, have invented new and useful Improvements inArresters, of which the following is a specification.

This invention relates to lightning arresters, end it has for its objectto simplify and im rove the construction of the some.

' ith these and other ends in view which will readily appear as thenatureof the inv-ention'is better understood, the seme cons sists in theimproved construction,and novel arrangement and combination of partswhich will be hereinafter fully described and partioulerly pointed outin the claim.

. In the drawings: Figure 1 is a side elevntion of a lightning orre torerJnst-rmrted in accorrlei'ice with the prim. tion. Fig. 2 is alongitudinal sectional view of the same. Fig. 3 is :1. transversesectional view taken on the plane indicated by the line 3'3 in Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of. reference.

The in'i-provedlightning arrester coin )rises in its construction atubular body 1 oi porcelain or other suitable non-conducting inateriol;upon the ends of said tubular body.

there are fitted heads 2, .2, likewise constructed of porcelain orsimilar min-conducting 1; said hennl being provided with reccssr it forengagemr with the ends of the tubular body. The Z are provided withexterior shoulders i with the ends of the tnhnlnr metallic casing 5, andthe hendsnro also provided with longid-rulinnl apertures (i for thepuss-ego oi? the ends ot a. wire con 7 which is wound uponv the ples ofthe invcnint engagement.

body 1 within the casing 5. The parts are assembled by a bolt or rod 8extending throu h the tubuler body 1 and through ecn trel aininapertures 9 in the heads 2, 2; the latter being provided withcountersinks 10 for therece tion of the bolt-heed. 11 end the nut 12. Te tubular metallic casing 5 is provided with a boss 13 having a threadedaperture for the reception of a screw 14 constituting a binding postwhereby the metallic casingfi is connected with the groundw'ire 15.

When the lightning 'errester has been properly installed currents ofexcessive p0 tentiel will break across the"gep between the coil 7 andthe casing 5 and passed to ground through the conductor 15.

I-[ev'ing thus described the invention what is claimed is:

The herein described lightning orrester, consisting of a longitudinallybored non-con dnctii'ig body, non-conducting heads fitted upon the endsof said body, and provided with countersunk ends, said heeds'hevinglongitudinal apertures therein, and external shoulders thereon, atubular metallic casing inc-losing the non-conducting body and ongo ingthe shoulders of the heads, a. heeded be t passing thru --;h, thenon-eornlucting body and hen-(ls end a nut on one em thereof, n wireextending through the heads endeoiled around the non conducting .body,and a. ground wire connected to the tubular easing by a. binding screw,substantially as specified.

In testimony whereof, I afiix my signature in presence of two witnesses.
